Frame of rod-like element parts, preferably for window frames and casements

Field of application of the invention

The invention relates to a frame made of rod-like individual parts, preferably for window sashes and window frames.

Characteristic of the known technical solutions

Known are such frames in which the individual parts of the window frame and the sash are connected to each other so that in ^ their 'end-' a so-called "'he läppt e> ^! Fork * pin" connection is milled, "where The covering surfaces are coated with adhesive, and these are combined by the application of a compressive force into casement frames or frames. Such a solution is iats. B. im. "Encyclopedia "ά'έτ Holzt öchnik ' ¹ ', 'VEB Fachbuchhandlung ^; , Leipzig, 1964, as well as in the book "specialist for""Schreiner"', publishing house' Willing Co. Wuppertal Bremen, Federal Republic of Germany, 1956, described ·

The above solution has the disadvantage that it requires complicated pressing and gluing facilities. Nevertheless, inaccurate '' pressing '' often occurs _; ; - before.,;, - besides ""dripping; the adhesive still has the unpleasant consequence that in the assembled frame there are spatial and dimensional inaccuracies, which only result from additional workload, 2 '. B * Schleifeh, Schlichten and the like can be eliminated. "In addition, it comes as a complicating factor that the frame is difficult to move in a composite state, and this requires a further expenditure of energy, labor and costs, as well as space-needing facilities.

Another Hachteil the 'above' method is that often discarding the custom-made as individual parts prefabricated construction elements after folding of the

30 * 8.1982 60 497/23

assembled frame. Often, 50 % of the original cross-section of the individual rods is removed by this folding, so that the internal stress forces of the material, which have been in equilibrium until then, often change into undesirable deformations even in the case of individual parts of impeccable quality and with best production technology. as a consequence - Qualities J deteriorations occur.

In the manufacturing industry for metal and plastic windows, such frames are also known in which the bar ends of Slementarteile 'sawed off window frame and sash at an angle of 45 °, then the cut surfaces mated together and the Änchchuußkanten welded together who. This assembly process has the "defect" that the welds can be subsequently processed only with injury "of Sinselteil- surfaces, and that the resulting surface defects can only very 'cumbersome - can be eliminated - by subsequent processing - what ν also a repeated move requires the rather heavy frame *

The above-mentioned solutions also have the common disadvantage that, because of the phenomena which appear only after assembly, the surface treatment... painting and / or varnishing, only at the composite frame, durckge.führt, can be. After grinding, the sanding ϊ can not be done on the finished frame after drying the individual lacquer shims, or only on a very expensive basis. However, if you omit the grinding operations, you get frame surfaces inferior quality.

In another Ausiüariings at play to Pig. 9 to 11 there is a deviation only in the embodiment of the clamping bolt · 12; In FIG. 9, the fixing unit 3 can be seen in an open position, but in FIG. 10 in a closed position. The transverse holes TO; 11 are similar to Fig. 8 as blind ^) holes designed. The clamping bolt 12; 13 are in the present case on a ausammengespannten, with the transverse bores 8; 9 of the connecting piece 4 cooperating clamping pin part 19 as an eccentric pin with an eccentricity e (Fig. 9). The clamping bolt 12; 13 are provided at their upper end for attaching a screwdriver with a groove 20.

In Fig. IT, the fixing unit 3 is seen in the closed, compressed state »For this purpose, the clamping bolt 12; 13 twisted by almost 180 °. In the clamped position, the distance between the transverse bores 10; 11 from one another slightly smaller than about the value of the douOelte Eszentri- J quote e.

Finally, in Fig. 12 and 13, such a variant of the fixing unit 3 to see the frame, which as 7 / eiferentv / ick-ment of the solution, according to, Fig. 5 'considered ^, kaiin. Here, the clamping bolts 12 and 13 consist of a press screw 21, a · nut 22 and two on the pressing screw 21 mounted clamping sleeves 23 · The clamping sleeves 23 are designed conically at their mutually facing ends. To connect to the conical end of the clamping sleeves 23 ', the transverse bores 8; 9 of the connecting piece 4 from the center line-outward in both directions, as flared, "conical" bores made.

\ _j which always Irisier unit 3 attached two elementary parts to each other. Of course, according to the invention, such an embodiment is also possible in which the pixying unit 3 alone can also connect a plurality of frame components with one another ·.

The most important advantage of the frame according to the invention is that on the one hand the complete 'pre-production of the components, on the other hand their assembly with the proposed pixer units into frames of great strength' and 'dimensional stability' is made possible '. If necessary, connections can also be resolved . ' The dimension, shape and shape of the fabricated and W surface treated components j and their surface quality do not change either during assembly or after. Anode-finished 'frames are none at all: further rework is necessary. Thus, the components can be mass-prefabricated and taken in stock * However, if one compares the already carried out in the frame state Pabrika'Tions- and surface treatment circumstances, the proposed framework requires a much smaller 'effort, as well as Pertigungseinrichtungen of only much smaller space or space requirements. The relatively simple assembly of the completely prefabricated slab parts eliminates the complicated assembly routes used in the conventional manufacturing process which are often "short-lived". heavy material movement · The risk of subsequent damage
